VISE.

SPECIFICATION forming part Of Letters Patent NO. 432,918, dated July 22,1890.

Application filed December 6, 1389. Serial No. 332,850. (No model.)

To all whom it may concern:

Be it known that I, CHARLES WIES, a citizen of the United States,residing at Faulkton,in the county of Faulk and State of South Dakota,have invented a new and useful Vise, of which the following is aspecification.

My invention is an improvement in that class of Vises whose sliding jawis operated by a cam-lever pivoted on the fixed jaw and provided with apendent lip or flange that en gages shoulders or teeth formed on theshank of the sliding jaw.

The novel feature of my vise is the means for pivoting and detachablyholding the camlever on the fixed j aw,as hereinafter described.

In the accompanying drawings, Figure 1 is a perspective View of thevise; and Fig. 2 is a vertical section, enlarged, on line 2 2, Fig. 1.

The vertical fixed jaw Aand its horizontal extension or box A are formedintegrally. The vertical movable jaw B has a rectangular shank B, thatslides in the aforesaid parts A A in the usual way. The upper side ofthe shank B is constructed with straight shoulders or teeth that arearranged at a slight transverse angle to the axis of shank. Thehand-lever O, that operates the sliding jaw B, as hereinafter described,has an enlarged head provided with a circular opening, and a lateralprojection which constitutes a cam 0, adapted to engage the shoulders ofshank B. The said opening in the head of the lever 0 receives or fits ona pivot-pin D, which is formed integrally with the inclined upper sideof the box A. A flange D projects from the pivot-pin D toward the fixedjaw A. The lever-head fits and works somewhat loosely on and under thesaid pin D and its lateral flange D, so that it may be readily slippedover and under them, and may be tilted to disengage 49 the lip of camcfrom the teeth of "shank B, as shown by dotted lines in Fig. 2.

To operate the vise, the object to be clamped having been placed betweenthe jaws A and B, the latter is then pushed toward the former and intoclose contact with the object. The lever O is next moved to the left, sothat its cam c is forced against one of the teeth of shank B, which isthereby moved slightly,

thus drawing the jaw B nearer the fixed jaw, 50

as shown by dotted lines, Fig. 2, and firmly clamping the object in therequired manner. \Vhen it is desired to release the said object, thelever O is moved to the right to disengage its cam c from the tooth ofshank B, and its purpose specified.
